Laurent Pinchart 7cbb0e55e2 sh-pfc: Don't duplicate argument to PINMUX_GPIO macro
The PINMUX_GPIO macro takes a port name and a data mark, respectively of
the form GPIO_name and name_DATA. Modify the macro to take the name as a
single argument and derive the port name and data mark from it.

Laurent Pinchart 533743dccb sh-pfc: Replace pinmux_enum_id typedef with u16
The typedef only conceals the real variable type without bringing any
additional value (see Documentation/CodingStyle, section 5.b). Moreover,
it polutes the pinmux namespace. Replace it with the integer type it
used to hide.

Laurent Pinchart 2afb968126 sh-pfc: sh7785: Remove unused input_pu range
The PFC SH7785 SoC data contains a input_pu range used to configure
pull-up resistors using the legacy non-pinconf API. That API has been
removed from the driver, the range is thus not used anymore. Remove it.

If required, configuring pull-up resistors for the SH7785 can be
implemented using the pinconf API, as done for the SH-Mobile, R-Mobile
and R-Car platforms.

Laurent Pinchart a373ed0aa2 sh-pfc: Split pins and functions definition tables
Split the GPIOs table into a pins table for real GPIOs and a functions
table for function GPIOs.

Only register pins with the pinctrl core. The function GPIOs remain
accessible as GPIOs.

Laurent Pinchart caa5bac3b4 sh-pfc: Replace SoC info data and mark ranges with a number of pins
The data and mark ranges are only used to check whether a GPIO
corresponds to a real pin or a function. As pins come first in the list
of GPIOs and in the platform-specific GPIO enumerations, we can replace
the data and mark ranges by a number of pins.

Add an nr_pins field to struct sh_pfc_soc_info to store the number of
pins implemented by the SoC, remove the data and mark range fields and
introduce sh_pfc_gpio_is_pin() and sh_pfc_gpio_is_function() functions
to replace range-based checks.

Laurent Pinchart d7a7ca5781 sh-pfc: Replace first_gpio and last_gpio with nr_gpios
The SoC information first_gpio field is always equal to 0, and the
last_gpio field is the index of the last entry in the pinmux_gpios
array. Replace the first_gpio and last_gpio fields by a nr_gpios field,
and initialize it to ARRAY_SIZE(pinmux_gpios).

Laurent Pinchart 35ad42719e sh-pfc: Use GPIO_FN instead of PINMUX_GPIO where possible
The GPIO_FN macro expands to the PINMUX_GPIO macro. The regular
expression to 'unexpand' PINMUX_GPIO to GPIO_FN is

s/\tPINMUX_GPIO(GPIO_FN_\([A-Z0-9_]*\),[ \t]*\1_MARK)/\tGPIO_FN(\1)/

This consolidates SoC-specific PFC information to use the same macros
for all SoCs.
